title: Bone-like material growth in a replanted immature central incisor following avulsion.
abstract: BACKGROUND
  Avulsion is one of the most complicated types of trauma to the teeth. After replantation of an avulsed immature tooth, numerous pulpo-dentinal responses may occur.
  
  
  METHODS
  This study reports a case of a seven-and-a-half-year-old boy in whom an immature maxillary permanent central incisor was replanted following avulsion due to a fall from a tree, and a bone-like growth was observed in the pulp chamber 6 months after the trauma, with a thin radiolucent line on the inner surface of the dentinal walls. The bone-like structure eventually filled the pulp chamber of the tooth.
  
  
  RESULTS
  The tooth was followed up 4 years after the replantation with no evidence of pathology.
  
  
  CONCLUSIONS
  This case demonstrates an immature avulsed tooth which did not present positive vital signs, but still maintains the potential of survival, and endodontic intervention may not be required. Instead, follow-up visits are recommended as long as there are no pathologic signs, especially in teeth with questionable prognosis.
